Description
Technical field
The present invention relates to a kind of cardiac thoracic surgery apparatus, specifically a kind of automatic drag hook device for intracardiac operation under direct vision.
Background technology
Intracardiac operation under direct vision many employings mid-sternal incision, adds that complex structure, visual area is less, difficult exposure because anatomical cardiac position is dark.Often need assistant's with the hands intracardiac structure of tractive clinically, but tractive assistant Yi Fasheng is tired for a long time on the one hand, causes drag hook conjugate and affect surgical exposure, repeatedly adjust drag hook and waste operating time again; Assistant can occupy the space around visual area when carrying out tractive and exposing on the other hand, thus affects the operation of patient; In addition, assistant makes the operating process often cannot looking at visual area when with the hands tractive exposes straight, is unfavorable for Operation cooperation, both extends operating time, be also unfavorable for the progress of assistant's surgical technic, cause cardiac surgeon to grow up slowly.
Find through retrieval, name is called the Chinese invention patent of " automatic tractor for atrium sinistrum ", application number " 87214421.6 ", self-retractor is connected with sternal retractor by " work " font nail by this invention, this connection belongs to and is rigidly connected, once sternal retractor is opened in operation process, the drag hook adjusting range being arranged on top is just very little, and is difficult to remove or change drag hook in operation process; Due to misoperation, easily cause damage to the tissue in ambition, also need assistant to use drag hook to carry out manual cooperation for some darker operative sites, operation uses very inconvenience.
Summary of the invention
Technical problem to be solved by this invention is, for the shortcoming of above prior art, a kind of automatic drag hook device for intracardiac operation under direct vision is proposed, efficiently can be convenient to use self-retractor by auxiliary intracardiac operation under direct vision, and drag hook position can be flexible and changeable, the impact that assistant can be avoided to expose operating field, shortens operating time greatly.
In order to solve the problems of the technologies described above, the invention provides a kind of automatic drag hook device for intracardiac operation under direct vision, comprise Sternal distraction device and be located at the bracing or strutting arrangement on described Sternal distraction device, described Sternal distraction device comprises rack-plate, fixed arm and lever arm, described fixed arm and lever arm all by rectangular column shape for the top that supports and the forming for the bottom strutted of the arc shaped blade shape in outwards upset being connected to below an upper section, the one end on one end of described rack-plate and the top of described fixed arm is fixedly linked, one end socket on the top of described lever arm is arranged on described rack-plate, and form symmetrical structure with described fixed arm, thumb wheel with the gears meshing of described rack-plate is installed in the link of described lever arm and rack-plate, the rotating shaft of described thumb wheel is provided with rocking arm, driving thumb wheel to rotate by rocker arms roll makes described lever arm move left and right on described rack-plate, the upper surface on the top of described lever arm and/or fixed arm is provided with fixed installation bar, and described bracing or strutting arrangement is made up of a fixed block, two inverted "L" shaped bracing frames, a slide-bar and at least one drag hook slide block, described fixed block is rectangular column shape and its bottom surface is provided with the draw-in groove corresponding with described fixed installation bar, and described fixed block is connected on described fixed installation bar by its draw-in groove, described inverted "L" shaped bracing frame has vertical portion and horizontal part, the vertical portion of two inverted "L" shaped bracing frames lays respectively at the two ends of described fixed block and protrudes upward, and the horizontal part of cantilever is extended on top, vertical portion to the direction of the lever arm or fixed arm that are positioned at its side, between the horizontal part that described slide-bar is connected to two inverted "L" shaped bracing frames that one end away from vertical portion, described drag hook slide block is arranged on described slide-bar and slides, and described drag hook slide block has the installing hole and fixed bolt hole of installing atrium drag hook or ventricle drag hook, described drag hook slide block and slide-bar is connected and fixed by the clamping screw in described fixed bolt hole.
